Paper on the impact of dropwindsondes from the Global Hawk on forecasts released online in Monthly Weather Review

Summary: 

A drone, what we call an unmanned aircraft system, can collect data in tropical cyclones (TCs) to improve forecasts.  Scientists have used the Global Hawk drone that can fly at an altitude of up to 60,000 feet for over 24 hours at a time since 2010. 181 more words

HRD Seminar – Dr. Andrew Hazelton, NOAA/GFDL, Princeton, NJ – 29 May 2018

Dr. Hazelton presented a seminar titled “High-Resolution fvGFS Forecasts of Atlantic Tropical Cyclones: Structural Analysis and Evaluation of the 2017 Atlantic Hurricane Season”.

ABSTRACT:

As numerical models reach finer horizontal and vertical resolution, evaluation of storm structure is critical to model assessment and improvement.   287 more words
